P-hydroxybenzoic acid positively affect the Fusarium oxysporum to stimulate root rot in Panax notoginseng.

ABSTRACT:

Background

Plant health is directly related to the change in native microbial diversity and changes in soil health have been implicated as one of the main cause of root rot. However, scarce information is present regarding allelopathic relationship of Panax notoginseng root exudates and pathogenic fungi Fusarium oxysporum in a continuous cropping system.

Methods

We analyzed P. notoginseng root exudate in the planting soil for three successive years to determine phenolic acid concentration using GC-MS and HPLC followed by effect on the microbial community assembly. Antioxidant enzymes were checked in the roots to confirm possible resistance in P. notoginseng.

Results

Total 29 allelochemicals in the planting soil extract was found with highes
